Making own function-CodePudding

I am trying to create a basic function in Python. Below you can see my code:

# Create function
def return_value_fun(type_1,type_2):
    if type_1 < 0:
        return 0
    else:
        return type_1-type_2

# Testing function
return_value_fun(100,100)

This function working well. Now I want to put an additional argument tb into the function you can see below:

# Create function
def return_value_fun(type_1,type_2,tb):
    if type_1 < 0:
        return tb = 0
    else:
        return tb = type_1-type_2

# Testing function
return_value_fun(100,100)

Additional arguments make this function to not work. So can anybody help me how to solve this?

I'm unclear as to what you're trying to do, but if you want to store the returned value inside a variable, it can be done like this:

# Create function
def return_value_fun(type_1,type_2,tb):
    if type_1 < 0:
        return 0
    else:
        return type_1-type_2

# Testing function
tb = return_value_fun(100,100)

Answer is :

# Create function
def return_value_fun(type_1,type_2):
    if type_1 < 0:
       tb = 0
    else:
        tb=type_1-type_2
        return tb
